Built around RKI Instruments' latest smart sensor technology, the SC-01 is a versatile, personal, single toxic gas monitor. The sensors are interchangeable and automatically recognized by the instrument. Weighing 7.6 ounces, it offers sensors for ammonia, carbon monoxide, chlorine, hydrogen sulfide, phosphine and sulfur dioxide. The SC-01's extender cable allows the sensor to be attached to the end of a 10-foot cable for remote monitoring and quick response. The large LCD display shows the gas reading, battery level, current time and will automatically backlight in alarm conditions. Standard alarm types include vibration, visual and audible alarms that can be set to latching or self-resetting.
